Spacesuits : A Visual Journey

The constellation of Orion is rich with impressive nebulas. Of the many interesting details that particularly draws the eye is Barnard’s Loop, the bright red circular filament arcing down from the middle. The bright orange star on the upper left is Betelgeuse, while the bright blue star on the lower right is Rigel. Other famous nebulas visible include the Witch Head Nebula, the Flame Nebula, and the comparatively small Horsehead Nebula. NASA-APOD, Stanislav Volskiy.
